      abstract     = {Optical properties of mid-infrared, Li-based nonlinear
                      crystals (NLC) are estimated under realistic experimental
                      conditions for high power lasers using the thermal imaging
                      method. The study focuses on crystals with relatively large
                      apertures for high energy and power applications that are
                      transparent in a broad spectral range (6–16 µm). For
                      this purpose, a high average power Yb:YAG laser amplifier
                      system was used that pumps the crystals and the thermal
                      response of the materials was recorded. An estimate of the
                      linear and nonlinear absorption coefficients of different
                      non-oxide crystals at the 1-µm pump wavelength along with
                      their nonlinear refractive index is provided. To the best of
                      our knowledge, linear and nonlinear absorption coefficients
                      are presented for the first time, including the nonlinear
                      refractive index of AGS, LGSe, LIS, and LISe. These optical
                      material properties are of utmost importance for
                      cutting-edge laser developments close to damage thresholds
                      since they affect the resulting beam quality and conversion
                      efficiencies of novel high power optical parametric
                      amplifiers operating in the long-wavelength mid-infrared
